Senior Test Automation Engineer (Python, API, Linux – Billing / Rating Systems)
UK – Remote / Hybrid | Permanent

We are recruiting a Senior Test Automation Engineer to join an engineering team building large-scale backend platforms used for billing, rating, and high-volume transaction processing across telecoms and financial-grade systems.

This is a backend-focused automation role centred on Python, APIs, and Linux environments. It is not a UI automation role and not a manual QA position.

Responsibilities

Design, build, and maintain Python-based automation frameworks for backend services

Develop and execute automated tests for APIs and service integrations

Create coverage for regression, negative, and backward-compatibility scenarios

Analyse requirements and define test strategies and test plans for complex backend systems

Investigate failures using logs, metrics, and debugging tools in Linux environments

Work closely with engineers to identify root causes and improve testability and reliability

Support testing of systems deployed in cloud and distributed environments

Essential Experience

Strong, hands-on experience in Python test automation

Proven background testing backend services and APIs

Confident working in Linux environments (CLI, logs, troubleshooting)

Experience testing billing, rating, charging, payments, or financial transaction systems

Solid understanding of authentication and authorisation (OAuth2, JWT, API keys, etc.)

Experience with CI/CD pipelines, version control, and defect tracking tools

Desirable Experience

Telecoms platforms (charging, mediation, invoicing)

SDK testing and contract testing

Performance or load testing exposure

Containers and cloud platforms (Docker, Kubernetes, AWS/Azure/GCP)

This role is not suitable for:

UI automation–focused profiles (e.g. Selenium/Cypress-first)

Manual-only QA roles

SCADA, hardware, or control-systems testing backgrounds

Right to Work

Applicants must have the legal right to work in the United Kingdom without visa sponsorship now or in the future. Unfortunately, sponsorship is not available for this role

Maths for Cloud Jobs: The Only Topics You Actually Need (& How to Learn Them)

If you are applying for cloud computing jobs in the UK you might have noticed something frustrating: job descriptions rarely ask for “maths” directly yet interviews often drift into capacity, performance, reliability, cost or security trade-offs that are maths in practice. The good news is you do not need degree-level theory to be job-ready. For most roles like Cloud Engineer, DevOps Engineer, Platform Engineer, SRE, Cloud Architect, FinOps Analyst or Cloud Security Engineer you keep coming back to a small set of practical skills: Units, rates & back-of-the-envelope estimation (requests per second, throughput, latency, storage growth) Statistics for reliability & observability (percentiles, error rates, SLOs, error budgets) Capacity planning & queueing intuition (utilisation, saturation, Little’s Law) Cost modelling & optimisation (right-sizing, break-even thinking, cost per transaction) Trade-off reasoning under constraints (performance vs cost vs reliability) This guide explains exactly what to learn plus a 6-week plan & portfolio projects you can publish to prove it.

Neurodiversity in Cloud Computing Careers: Turning Different Thinking into a Superpower

Cloud computing sits at the heart of modern tech. Almost every digital product runs on someone’s cloud platform – from banking apps & streaming services to AI tools & online shops. Behind those platforms are teams of cloud engineers, architects, SREs, security specialists & more. These roles demand problem-solvers who can think in systems, spot patterns, stay calm under pressure & imagine better ways to build & run infrastructure. That makes cloud computing a natural fit for many neurodivergent people – including those with ADHD, autism & dyslexia. If you are neurodivergent & considering a cloud career, you might have heard messages like “you’re too distracted for engineering”, “too literal for stakeholder work” or “too disorganised for operations”. In reality, many traits that come with ADHD, autism & dyslexia are exactly what cloud teams need. This guide is written for cloud computing job seekers in the UK. We will cover: What neurodiversity means in a cloud context How ADHD, autism & dyslexia strengths map to cloud roles Practical workplace adjustments you can ask for under UK law How to talk about neurodivergence in applications & interviews By the end, you should have a clearer sense of where you might thrive in cloud computing – & how to turn “different thinking” into a professional superpower.

Cloud Computing Hiring Trends 2026: What to Watch Out For (For Job Seekers & Recruiters)

As we move into 2026, the cloud computing jobs market in the UK is shifting again. The era of “lift & shift everything to the cloud” is giving way to a more mature, cost-conscious & security-focused phase. Many organisations are tightening budgets, some are rationalising cloud spend, yet demand for strong cloud talent remains high – especially around multi-cloud, FinOps, cloud security, data platforms & AI on cloud. Vendors are racing to integrate generative AI into their offerings, enterprises are modernising legacy estates, & regulators are asking tougher questions about resilience, sovereignty & risk. At the same time, some roles are being automated or commoditised, & the bar for cloud roles keeps rising. Whether you are a cloud job seeker planning your next move, or a recruiter building cloud teams, understanding the key cloud computing hiring trends for 2026 will help you stay ahead.
